A question on GBUDB utilization. I show a current utilization of 95%
(from the log file) which I assume means the amount of memory used
from what is set aside for gbudb entries. Is that correct?
Yes.
What happens when more entries are added? Does the GBUdb grow or
does it get pruned out?
Both. When more space is needed the ram allocated to GBUdb will grow to
accommodate the need. This should happen infrequently. When entries are
no longer active they are dropped to make room for additional entries.
In practice the GBUdb data size stabilizes quickly and then doesn't
change much.
Once per day or as otherwise specified by GBUdb condensation triggers
the GBUdb data will be condensed. This means that all of the good and
bad event counts are divided in half. This has the effect of retaining
the ratios (probability of spam) while reducing the event counts
(confidence figure). Any ugly entries that drop to zero are dropped from
the system (forgotten). The remaining live entries are placed in a new
GBUdb and the old one is thrown away. If the GBUdb size can shrink
during a condensation run then it will.
Will gbudb XCI commands (like <bad>) show up in a log file?
No. These are administrative entries so they don't get reported in scan
activity. We may change this later but at present there are no requests
for it.
Best,
